IocApi.js

ioc('parent', function(component, parentElement){
  parentElement.click(function() {
    component.parentClicked();
  });
});

ioc('component', function(componentElement) {
  componentElement.click(function() {
    alert('component clicked');
  });

  this.parentClicked = function() {
    alert('parent clicked');
  };
});

ioc('parent');

Still tweaking the usage. had some inspiration this weekend ;)
